Artek X602 stool, design by Alvar Aalto. Birch with black faux leather upholstery, beautiful fan legs, and wonderful patina of time. The stool is from 1950s, and has original upholstery attached with original nails. The stool is in good condition. I have official proof of authenticity such as vintage catalogs, designer records, or other literature sources and take full responsibility for any authenticity issues arising from misattribution
